flash point and is not flammable in air. Fossil Fueled. Fuel containing chemical energy, which has been formed from animal and plant matter over many years (., oil, coal, and natural gas) that are used in a boiler to produce steam for the generation of electrical energy. High Fire Point Liquid. A bustible dielectric liquid listed as having a fire point of not less than 572176。 F (300176。 C). High Voltage Direct Current (HVDC) Converter Station. A facility that functions as an electrical rectifier (acdc) or an inventor (dcac) to control and transmit power in a high voltage work. There are two types of HVDC valves — the mercury arc valve and the presentday technology solid state thyristor valve. Both types of valves present a fire risk due to high voltage equipment that consists of oilfilled converter transformers, wall bushings, and capacitors in addition to various polymeric ponents. Interior Finish. The exposed interior surfaces of buildings including, but not limited to, fixed or movable walls and partitions, columns, and ceilings. Interior finish materials are grouped as Class A Interior Finish and Class B Interior Finish. Interior Finish, Class A. Materials having flame spread 025, smoke developed 0450 when tested in accordance with NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials. Includes any material classified at 25 or less on the flame spread test scale and 450 or less on the smoke test scale when any element thereof, when tested, does not continue to propagate fire. Interior Finish, Class B. Materials having flame spread 2675, smoke developed 0450 when tested in accordance with NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials. Includes any material classified at more than 25, but not more than 75, on the flame spread test scale and 450 or less on the smoke test scale. Labeled. Equipment or materials to which has been attached a label, symbol, or other identifying mark of an anization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates pliance with appropriate standards or performance in a specified manner. Limited Combustible. As applied to a building construction material, a material not plying with the definition of nonbustible material that, in the form in which it is used, has a potential heat value not exceeding 3500 Btu/lb ( 106 J/kg) (see NFPA 259, Standard Test Method for Potential Heat of Building Materials), and plies with one of the following: (a) materials having a structural base of nonbustible material with a surfacing not exceeding a thickness of 1/8 in. ( mm) that has a flame spread rating not greater than 50。 or (b) materials, in the form and thickness used, other than as described in (a), having neither a flame spread rating greater than 25 nor evidence of continued progressive bustion, and of such position that the surfaces that would be exposed by cutting through the material on any plane would have neither a flame spread rating greater than 25 nor evidence of continued progressive bustion as tested in accordance with NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials. Materials subject to increase in bustibility or flame spread rating beyond the limits herein established through the effects of age, moisture, or other atmospheric condition are considered bustible. Liquid, Less Flammable. A bustible dielectric liquid listed as having a fire point of not less than 572176。 F (300176。 C). * Listed. Equipment, materials, or services included in a list published by an anization that is acceptable to the authority having jurisdiction and concerned with evaluation of products or services, that maintains periodic inspection of production of listed equipment or materials or periodic evaluation of 中国最庞大的资料库下载 Copyright NFPA 中国最庞大的资料库下载 services, and whose listing states that either the equipment, material, or service meets appropriate designated standards or has been tested and found suitable for a specified purpose. Mass Burn. A process in which municipal solid waste is hauled directly to a tipping floor or storage pit and then is used as a boiler fuel without any special processing. Municipal Solid Waste (MSW). Solid waste materials consisting of monly occurring residential and light mercial waste. Nonbustible. A material that, in the form in which it is used and under the conditions anticipated, will not aid bustion or add appreciable heat to an ambient fire. Materials when tested in accordance with ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750176。 C, and conforming to the criteria contained in Section 7 of the referenced standard are considered nonbustible. Refuse Derived Fuel (RDF). A boiler fuel manufactured by means of a process that includes storing, shredding, classifying, and conveying of municipal solid waste. Should. Indicates a remendation or that which is advised but not required. 15 Units. Metric units in this document are in accordance with the International System of Units, which is officially abbreviated SI in all languages. For a full explanation, see ASTM SI 10, Standard for Use of the International System of Units (SI): The Modern Metric System. Chapter 2 Fire Risk Control Program 21 General. This chapter provides remended criteria for the development of a fire risk control program that contains administrative procedures and controls necessary for the execution of the fire prevention and fire protection activities and practices for electric generating plants and high voltage direct current converter stations. The fire risk control program remen。
